北京地铁6号线下穿既有4号线线路及隧道远程监测

Remote Monitoring on Existing Line 4 during Line 6 Under-Passing Construction in Beijing Metro

北京地铁6号线平安里站—北海北站区间采用矿山暗挖法下穿既有地铁4号线,为保证既有4号线运营安全,应用远程自动化监测系统对既有4号线的隧道结构及线路进行实时监测,通过施工期间的实时监测,快速反馈信息,指导施工,保障了新建6号线的顺利下穿和既有4号线的运营安全。

When Beijing metro line 6 under-passed existing metro line 4 in the section of Ping＇anli station Beihai North station by using mine tunneling method, in order to ensure tile safe operations of metro line 4, real-time monitoring is carried out on existing Line 4 line tunnel structure and track by using remote automatic monitoring system. By real-time monitoring during construction, rapid feedback guides the construction to ensure of smooth under-passing of existing line 4 and safe operation of new line 6.
